BURNER;

To a-ZZ whom 'it may concern:

Be it known that I, GEORGES CosMovIci, `director of the Roumanian state railways,

"subject of the King of Roumania, residing at Bucharest, in the Kingdom of Roumania, have invented a new and Improved Burner; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to burners for burning liquid fuels, and more especially crude petroleum and its residues in` furnaces whereby both the fuel and the sucking medium (steam, air or the like) are supplied by two superposed chambers.

According to the invention the outlet of theA gas chamber is widened towards the front-end, whereby the issuing vapor sheet and hence the flame are dischar ed in fanform which form permits of istributing the flame over the whole fire-box. By provision of outwardly divergin bridge-pieces in the front-end part of the el conducting chamber the issuing liquid-sheet and the fan-like flame can be dividedinto several branches, the space between these branches growing continually vwider towards the front on account of the divergency of the forementioned bridge-pieces, the air having access into the interior of the flame between the branches, thereby insuring complete combustion of the burning fuel `without requiring a strong draft or the production of a long flame. importance for boilers.

In liquidfuel burners of known constructions the liquid-fuel, usually issuing through a nozzle, is finely divided by a jet of steam or air so that the flame forms a hollow cone to which the air has access only along the surface and consequently a complete combustion of the liquid fuel is not arrived at. It has been found `frequently necessary to introduce a supplementary amount of air into the flame cone, or to arrange an incandescent wall within the reach of the flame,

These features are of great locomotives and tubular i to insure' better combustion, nevertheless such arrangements have the great disadvantage of produciner smoke and soot.

A practical embodiment of theinvention is represented in the accompanying drawings forming a part of this spec1ficat1on, in

which similar; characters of "reference indicate corresponding parts in all the views.'

Figure 1 is a longitudinal sectional elevation of the burner Fig. 2 is a plan view of the same; Fi 3 isa cross section of the same, on the line 3 3 of Fig. 1, looking in the direction ofthe arrow and Fig. 4 1s a front view of the burner-outlet part.

The casing A is preferably fiat in cross section and is provided in a well known manner with superposed chambers B and C of which the lower one B serves for admission of liquid fuel and the upper one C for conducting the sucking medium (steam, air and the like). The rear end of the chamber B preferably is enlarged near the entranceport D of the liquid fuel in a downward direction, to form a pocket B for the accumulation of the water contained in the liquidfuel. The pocket is provided with an outlet B2 which as shown inv the drawing is closed by a plug b. 'The forward end of the chamthe stays Bfl and vprojecting upwardly andl outwardly beyond the outlet plane. The space betweenthe ribs B is growlng continuously wider in the direction of the ejected steam and the vapor sheet rushing over the outlet plane of the liquid fuel takes up 'the fuel by suction, atomizes it over a large surface and may even be divided ina similar manner into several branches.

The gas chamber C arranged above the fuel chamber B has a narrow outlet C2 which grows wider towards. its frontend, the issuing fiat vapor sheet spreading out in a fan-like shape and permitting of being distributed over the whole space wherein combustion takes place if the divergency of the lateral walls of the casing be suitably chosen. The burner tip consists of two parts, the fuel duct B3 and the superposed detachable steam duct C which are connected by bolts. 4

The vapor or air-jet, discharged from the outlet in the Ishape of thin branches, sweeps leov f over the liquid fuel pressed up to the borders'of the outlet-opening, taking up the fuel and extending in shape of a fan, the produced flat flame filling hereby completely the fire-box.

To allow the cleaning of the outlet C2 which sometimes becomes choked by im: purities and the like, a lmife H is horizontally and slidably arranged in the gas'chamber C and shaped in accordance tov the inner space of the burner outlet and guided in grooves provided in the chamber C. The horizontal displacement of the knife H may be effected, for example, by means of a lever L engaging a rod M carrying the said knife, the operation of the said lever governing a forward or f backward movement of the knife, the( forward movement making the knife enter into the outlet C2 and thereby remove outwardly the deposited impurities. Of course provisions` may be made for an automatic and continuous movement of the knife during the operation of the burner.

When steam is shut of,'the steam left in the chamber C condenses; in order to provide an outlet for the water due to condensed steam, the'lrear end of the chamber is provided with a boss F with which is ccnnected a valve pipe f, which also serves to The steam left in the chamber C Y while condensing, when being shut ofi', is

liable to draw in liquid-fuel by wayjof the outlet C2 and in order to prevent this it is suiiieient to shut off the' oil inlet and then to let thewater escape through the opening B2, out of the pocket B', the water having been separated from oil, the large heating surface of the fiat chamber C assistingsuch separation. To a boss G at the rear end of the chamber B,is connected a valve pipegto vpermit of cleaning'this chamber,` of blowing out the separated water and also of heating before starting the opera-tion. In order to adjust the length of the flame, it is suflicient to replace the detachable part B3 C by another suitably shaped part of differing I width.

What I claim asl my invention, and desire to secure by Letters Patent, is: v 1

1. A liquid fuel burner having a fuel chamber and a superposed steam chamber, each chamber having a separate fan-shaped outlet, 'the outlets being in the same plane and the fuel outlet having diverging stays whereby the liquid fuel is dividedl into several branches, substantially as described.

2. A liquid fuel burner having a fuel vposed steam chamber,

chamber and a superposed steam chamber each chamber having a separate fan-shaped outlet and the first outlet having diverging stays provided with outwardly diverging ribs projecting into the mouth of the steamchamber, substantially-'as described.

3. A liquid fuel burner having a fuel chamber and a superposed steam chamber, and a burner tip for said chambers, detachably secured to said chambers and provided with separate, fan-shaped steam and fuel outlets, the fuel outlet being subdivided by outwardly diverging ribs, substantially as described.

4. A liquid fuel burner having a fuel chamber and a superposed steam chamber and a removable lburner tip for said chambeil fue provided' with fan-shaped steam and outlets, said burner Atip being formed of an upper and a lower part, the lower part carrying upwardly protruding and outwardly diverging ribs, substantially as described.

5. A liquid f uel burner comprising a flat body having a fuel chamber and a supereach having a fanshaped outlet, the fuel chamber extending from the rear end of the steam chamber beyond theforward end of the same and having its rear end enlarged forming-a downwardly extending pocket having a water outlet, substantially as described.

6. A liquid fuel, burner chamber and a superposed steam chamber, each having aA fan-shaped outlet, in combination with a fan-shaped cleaning blade in the steam chamber and working in the, loutletthereof to keep the same clean, a reciprocable rod to which the blade is secured, and means for moving the said rod forward and backward, substantially as described.

7. A liquid fuel burner comprising a steam duct, a reciprocable cleaning blade in the said ssteam duct, afuel duct having a downwardly extending pocket at the rear end thereof, and a removable burner tip provided with separate outlets for the steam and the liquid fuel, the fuel outlet having stays carrying upwardly wardly diverging ribs, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
